IMPROVEMENT IN WAGON-BED LIFTERS.

Specification forming part of Letters Patent No. 141,669, dated August 12, 1873; application filed May 19, 1873.

To all whom it may concern:

Be it known that I, DAVID ROOD, of Moun Erie, Wayne county, State of Illinois, have invented a machine to take off and put on wagon-beds or other bodies, of which the following is a specification:

My invention is in a combination of roller, ratchet, spring, and pawl.

M-is the frame of the machine. 0 is a roller for the purpose of raising and lowering. The ropes are wound upon the roller O by means of ratchet and lever. P I, the ropes, pass over four pulleys, J, and pass low enough to come to the bottom of the wagon-bed, and are attached to slats underneath the bed. The ratchet is put on the same journal that the roller runs on, and the lever is attached to the same journal by means of two stirrups-one on each side of the ratchet. The stirrups are fastened to the lever by two rivets. The spring B is attached to the lever by two screws, and so bent at the top end that it will fit the teeth in the ratchet. G is a pawl with one end fastened to the top of frame M. The pawl is to fall into the teeth of the ratchet by the forward motion of the lever. In the backward motion of the lever the spring travels back over the teeth of the ratchet. Two beams, F

F, fasten into the center to the tie N. The

ropes P P pass around the roller and over the pulleys J in the end of the beam.

By pressure on the rope that is attached to the brake-lever the weight is held up until the pawl G is thrown out of gear by means of a small rod, which is raised and fastened over a hook 011 the frame M, and the spring is thrown out of gear by a small lever attached to the main lever by taking off the pressure of the brake-rope, which allows the wagonbed to come down slowly.

I claim as my invention- In the device for raising and lowering a wagon bed or frame or other bodies, the combination of frame, roller, ratchet and pawl, spring, lever, and ropes, substantially as herein set forth, and for the purpose specified.
